The device is used in Ethernet switches and Midspans to enable network devices to share power and data over the same cable. PD69012 device is a 12-port, mixed-signal, highvoltage Power over Ethernet driver. It enables detection of IEEE802.3af-2003 compliant PDs (Powered Devices) and IEEE802.3AT High Power Devices, thus, ensuring safe power feeding and disconnection of ports. With full digital control via a serial communication interface and a minimum of external components, the device integrates into multiport and highly populated Ethernet switches and routers. The PD69012 executes all real time functions as specified in the IEEE802.3af-2003 (“AF”) standard and IEEE802.3at High Power (“AT”) functionality, including load detection, “AF” and “AT” classification and port status monitoring. In addition it performs system level activities such as: power management and MIB support for system management. The PoE device is designed to detect and disable disconnected ports utilizing both DC and ...
